Fragment splicing is a primary strategy in the design and optimization of leading compound toward new skeleton with target bioactivity. Herein a series of novel substituted phenyl oxazole derivatives were designed via fragment analysis and coupling strategy that led to highly potent and bio-selective herbicide safener. The biological tests showed that most of the compounds could enhance the maize growth index, glutathione content and anti-reverse enzyme glutathione S-transferase activity in vivo. The molecular docking model exhibited that the novel compound could compete with chlorsulfuron binding to the herbicide target enzyme, which consequently attained the herbicide detoxification. Especially compound I-f displayed the best activities than commercial safener isoxadifen-ethyl and other compounds. The present work demonstrates that the synthesized compounds could be developed as potential candidates for the discovery of novel herbicide safeners in the future.

The intramolecular version of nucleophilic addison of phosphites to imines was carried out for the first time taking as an example β-aldimino-alkylphosphites, formed from chlorophosphites and β-aldiminoalcohols [N-(benzylidene)-2-aminoethanol and R-(+)-N-(benzylidene)-2-aminobutanol-1]. In these reactions, stereoisomeric 1,4,2-oxazaphospho-rines were obtained in good yields. R-(+)-N-(benzylidene)-2-aminobutanol-1 being used as a precursor, nucleophilic attack by P(III) atone on electrophilic C atom of the C=N group proceeds stereospecifically with participation of only re-face of the two possible diastereotopic faces of the imine double bond to give the epimeric at phosphorus (3R, 5R)-2-(β-chloroethyl)-2-oxo-3-phenyl-5-ethyl-1,4,2-oxazaphosphorines as precursors of nonracemic α-aminophosphonic acids.
Regioselective generation of iminium cation by PET processes: Its in situ trapping by intramolecular nucleophiles and synthesis of some biologically active heterocycles
Pandey,Kumaraswamy,Yella Reddy
, p. 8295 - 8308 (2007/10/02)
Efficient, mild and direct route for regiospecific iminium cation is developed by sequential two electron oxidation of several N-alkylated tertiary amines by photoinduced electron transfer processes. The regiospecificity of iminium cation arises from the deprotonation step of amine radical cation to generate α-amino radical which depends on the stereoelectronic factor subject to kinetic acidity of amine radical cation. Iminium cation is efficiently trapped in situ by internal nucleophiles to give cyclic compounds 14-18 and 22a-c. Stereoselective synthesis of cis α,α'-dialkylated piperidines and pyrrolidines 30a-c is achieved by nucleophilic opening of tetrahydro-1,3-oxazines 22a-c.
